Well it shouldn't be surprising, as Rust's enum behaves pretty much like a C/C++ one if all cases are nullary. The only changes are syntactical ("EnumType::Variant" instead of just "Variant", unless you "use EnumType::*"). In fact, it's exactly because they didn't want to be surprising that they used "enum" instead of something else, like "data" in Haskell.
